Estimation of Local Delamination Buckling in Orthotropic Composite Plates Using Kirchhoff Plate Finite Elements

Table 2

Difference between the critical amplitudes of the constant and sine loaded plate, and the difference between the two types of loads of each method (), and the difference between the results of the ABAQUS model with sinusoidal loading and the results of the present method (). The dimensions of the results are in N mm−1.
